An MPPT solar inverter (Maximum Power Point Tracking solar inverter) is a power conversion device that continuously adjusts the operating voltage and current of photovoltaic (PV) panels to ensure they operate at their maximum power point under changing sunlight and temperature.
A dual-axis tracker is a device that tracks the sun's movement along two axes (horizontal and vertical) to maximize the amount of sunlight captured by solar panels.
Lithium-ion batteries have higher voltage than other types of batteries, meaning they can store more energy and discharge more power for high-energy uses like driving a car at high speeds or providing emergency backup power.
Solar panels are rated for hail impact which is roughly the impact of a 1" hail ball striking the panel at 52 mph. The tempered glass protects the solar cells under this type of impact.
